(3, 2), y = x + 5 Write an equation in slope-intercept form for the line that passes through the given point and is parallel to the graph of the given equation.
Answer:
y = x - 1
Step-by-step explanation:
Since the line is parallel to y = x + 5, it will have the same slope, which is 1.
Plug in the slope and the given point into y = mx + b, and solve for b:
y = mx + b
2 = 1(3) + b
2 = 3 + b
-1 = b
Then, plug in the slope and b into the equation:
y = mx + b
y = x - 1
So, the equation is y = x - 1
The equation of the line in slope-intercept form is: y = x - 1
What is Slope-intercept Equation?The equation of a line, where m is the slope and b is the y-intercept, is modelled by the equation, y = mx + b.Slope of parallel lines will be the same.Thus, the slope (m) of the line that is parallel to y = x + 5 will be 1.
Write the equation of the line by substituting (a, b) = (3, 2) and m = 1 into y - b = m(x - a):
y - 2 = 1(x - 3)
Rewrite in slope-intercept form:y - 2 = x - 3
y = x - 3 + 2
y = x - 1
Therefore, the equation of the line in slope-intercept form is: y = x - 1.

Pira drives 825 miles to California. The trip takes 17 hours. He uses 38 gallons of gas on the trip which cost $125. What is the unit price he paid for gas
Answer:
a) His average speed is $48.53 miles/hour
b) His gas mileage is 21.71 miles per hour.
c) 1 gallon of gas is 1 gallon of gas = $3.29.
Step-by-step explanation:
A) Pira drives to California in 17 hours = 825 miles
Pira drives to California in 1 hours = (825/17) miles
= 48.53 miles/hour.
Therefore, his average speed is $48.53 miles.
B) Pira uses 38 gallons to drive 825 miles
Pira uses 1 gallon to drive 825/38 miles-per-hour
= 21.71 miles-per-hour
Therefore, his gas mileage is 21.71 miles per hour.
C) 38 gallons of gas cost = $125
1 gallon of gas = $125/38
1 gallon of gas = $3.29.

It has long been reported that human body temperature follows a normal distribution with a mean of 98.6 degrees Fahrenheit. There is some debate in the medical field, however, about this long-held standard of human body temperature. Specifically, some medical researchers believe that the average human body temperature is actually greater than 98.6 degrees Fahrenheit. To test their theory, these researchers measured the body temperature of a random sample of 180 healthy individuals. The researchers then recorded the mean and standard deviation for the sample of 180 individuals. After the researchers collected their data, they entered the data into a statistical software package and ran the appropriate statistical test which resulted in a test statistic of 3.64 with a p-value of .018. The researchers would conclude that:
Solution :
The normal body temperature of any human body is considered to be 98.6[tex]$^\circ \ F$[/tex]. But there is a constant debate about the body temperature of a long held standard to the body temperature.
It is given that :
Null hypothesis and alternate hypothesis :
[tex]$H_0 : \mu = 98.6$[/tex]
And [tex]$H_A : \mu > 98.6$[/tex]
n is given as = 180
Test statistics = 3.64
Prove = 0.018 < α = 0.05 (let reject null hypothesis for α = 0.05 )
Therefore, their results are statistically significant and the result is unlikely due to chance alone.

A hemispherical tank is filled with water and has a diameter of 17 feet. If water weighs 62.4 pounds per cubic foot, what is the total weight of the water in a full tank, to the nearest pound?
Answer:
The total weight = 1286 × 62.4 = 80246 pounds.
Step-by-step explanation:
The formula of the volume of the sphere is
V = 4/3×π×r³
Given
d = 17 feet
as
d = 2r
so
r = d/2 = 17/2 = 8.5 feet
as
V = 4/3×π×r³
Since we need half of the volume as it is a hemispherical tank.
[tex]\frac{V}{2}=\pi r^3[/tex]
[tex]=\frac{2}{3}\times \:3.14\times \:8.5^3[/tex]
= 1286 ft³
Given that the weighs 62.4 pounds per cubic foot
Thus,
The total weight = 1286 × 62.4 = 80246 pounds.
The total weight of the water in a full hemispherical tank, which is filled with water, is 80,260 pounds.
What is the volume of hemisphere?The volume of the hemisphere is the amount of quantity, which is obtained by it in the 3 dimensional space.
The volume of the hemisphere can be calculated with the following formula.
[tex]V=\dfrac{2}{3}\pir^3[/tex]
Here, {r} is the radius of the hemisphere.
A hemispherical tank is filled with water and has a diameter of 17 feet. The radius of the hemisphere will be half of the diameter. Thus,
[tex]r=\dfrac{17}{2}\\r=8.5\rm\;ft[/tex]
The volume of the hemispherical tank is,
[tex]V=\dfrac{2}{3}\pi(8.5)^3\\V=1286.22\rm\; ft^3[/tex]
The water weighs 62.4 pounds per cubic foot. Thus, the total weight of the water in a full tank is,
[tex]W={1286.22}\times62.4\\W=80260\rm \;pounds[/tex]
Hence, the total weight of the water in a full hemispherical tank, which is filled with water, is 80,260 pounds.

A florist has ordered 632 roses for valentines day. if the roses are divided into 50 bouquets, how many will each roses bouquet have, and how many roses will be left over. (show your work)
Answer:
12 in each bouquet, 32 left over
Step-by-step explanation:
You can solve this my long division where remainder is 32. Or you can reason this, since 50 is an even number, the total must be _00 or _50. The largest is 600. so 600/50 is 12, that means 632-600 is 32 roses left
